e. f/ L'.; I 4 22 l if, f 2| 3 it reaches the level of the secondary air inlets I9. Combustion takes place at or above the level of the secondary air inlets I9 and the llame and products of combustion pass into the interior of the heater I.

We claim:

1. In a pot type liquid fuel burner, a vertical burner pot having a closed bottom and an apertured top wall, a wall structure joining them, having a generally upright, imperforate fuelvaporizing panel, and a perforate air-admission portion having primary air inlet apertures located at various levels in, and distributed substantially from side to side of, the perforate portion, adapted to direct jets of primary air toward the vaporizing panel, said portion also having a horizontally disposed row of secondary air inlet apertures located below the top wall and above the primary air inlet apertures, means for supplying liquid fuel to the inner surface of the l panel below thev secondary air inlet apertures and above the primary air inlet apertures, whereby it may ow freely by gravity down the panel to and through the area within which the primary air inlet apertures direct their air jets toward the vaporizing panel.

2. In a pot type liquid fuel burner, a vertical burner pot having a closed bottom and an apertured top wall, a wall structure joining them, having a generally upright, imperforate fuel-vaporizing panel, and a perforate air-admission portion having primary air inlet apertures located at various levels in, and distributed substantially from side to side of, the perforate portion, adapted to direct jets of primary air toward the vaporizing panel, said portion also having a horizontally disposed row of secondary air inlet apertures located below the top wall and above the primary air inlet apertures, means for supplying liquid fuel to the inner surface of the panel below the secondary air inlet apertures and above the primary air inlet apertures, whereby it may flow freely by gravity down the panel to and through the area within which the primary air inlet apertures direct their air jets toward the Vaporizing panel, the vaporizing panel being slightly inc-lined to the vertical from the upper portion inwardly toward the lower portion of the pot.

3. In a pot type liquid fuel burner, a Vertical burner pot having a closed bottom and an apertured top wall, a wall structure joining them, having a generally upright, imperforate fuelvaporizing panel, and a perforate air-admission portion having primary air inlet apertures located at various levels in, and distributed substantially from side to side of, the perforate portion, adapted to direct jets of primary air toward the Vaporizing panel, said portion also having a horizontally disposed row of secondary air inlet apertures located below the top wall and above the primary air inlet apertures, means for supplying liquid fuel to the inner surface of the panel below the secondary air inlet apertures and above the primary air inlet apertures, whereby it may ilow freely by gravity down the panel to and through the area within which the primary air inlet apertures direct their air jets toward the vaporizing panel, the vaporizing panel being generally planar and the perforate air-admission portion of the wall structure being generally curved.
